Bit 10: Limit_Condition –
reset when the Limit Switch changes from its active to inactive state, or when a Reset Errors Com-
mand is issued.
Bit 9: Invalid_Jog_Change –
ters that can be changed during a Jog Move are Programmed Speed, Acceleration, and Deceleration.
Bit 8: Reserved –
Bit 7: Driver_Fault –
temperature Fault. Even though the driver is enabled, it will not supply current to the motor until the
motor's temperature decreases to a safe value. At this point the fault will clear itself.
Bit 6: Connection_Was_Lost –
when the connection is re-established. The Input_Error bit will also be set. Note that this bit is not
set if the communication loss is on the protocol level, not the physical level.
Bit 5: Reserved –
Bit 4: Temperature_Above_90°C –
90°C. At this point, the heatsink temperature is typically near 83°C. If this bit trips often and you
want to lower the operating temperature of the unit, consider changing how the device is mounted, or
installing a fan to force additional airflow over the device.

Notes on Clearing a Driver Fault

A Driver Fault occurs when there is an over temperature condition. When a Driver Fault occurs, the
SMD17E2 will set bit 7 of the Status Word 1 word in the Network Input Data. Even though the driver is
enabled, it will not supply current to the motor until the motor's temperature decreases to a safe value. At this
point the fault will clear itself.
